Efficiency and cost of treating proximal ureteral stones: Shock wave lithotripsy versus ureteroscopy plus holmium:yttrium-aluminum-garnet laser
2004
Abstract Objectives To compare the success rates, cost effectiveness, and efficiency of ureteroscopy (URS) and extracorporeal shock wave lithotripsy (ESWL) for proximal ureteral stones. Methods In a retrospective manner, 220 patients who underwent treatment for proximal ureteral stones were included in the study. The patient records, radiographs, and billing statements of all patients treated for upper ureteral stones between January 1997 and June 2001 at Scott and White Memorial Hospital were reviewed. The patients were placed into two treatment groups according to the method of their stone’s initial treatment. The stones were categorized as less than 1 cm and 1 cm or greater. Results A total of 111 patients were in the ESWL group, 73 of whom had stones less than 1 cm, and 109 patients in the URS group, 81 of whom had stones less than 1 cm. In the URS group, 91% were successfully treated with one treatment intervention, and 55% of the ESWL group were successfully treated with their initial intervention ( P P P = 0.43). URS had significantly lower charges for the initial procedure ($7575 versus $9507, P P Conclusions The results of this study indicate that URS is more efficient and cost-effective for stones up to and larger than 1 cm with similar complication rates compared with ESWL.
